Abstract
The techniques described herein are configured to map a new security association to an active Internet Protocol (IP) Multimedia Subsystem (IMS) session subsequent to the occurrence of a connectivity interruption. In various examples, the connectivity interruption occurs in an access network that supports an IMS network. The new security association is established using an updated IP address that is configured for (e.g., assigned to) a mobile device after the connectivity interruption to the IMS session occurs. The techniques described herein improve network performance because less resources are spent to establish new IMS session in response to the interruption. Rather, in accordance with the examples provided herein, network components can determine that a new security association is associated with an active IMS session, and the network components can map the new security association to the active IMS session (e.g., one for which the IMS has not released the IMS bearer).
